Local area networks (LANs) connect devices within a small geographical area from "summary" of Data Communications and Networking by Behrouz A. Forouzan
Local area networks, or LANs, are a type of network that connects devices within a small geographical area. These networks are commonly used in homes, schools, and businesses to enable communication and resource sharing among devices such as computers, printers, and servers. By connecting these devices to a LAN, users can access shared resources and collaborate more effectively. One key characteristic of LANs is their limited geographical range. Unlike wide area networks (WANs) that can span large distances, LANs are typically confined to a single building or campus. This localized nature of LANs makes them well-suited for connecting devices in close proximity to each other. In a LAN, devices are connected using physical media such as Ethernet cables or wireless technologies like Wi-Fi. These connections allow devices to communicate with each other and share information. By establishing a LAN, organizations can create a networked environment where users can access shared files, printers, and other resources easily. LANs also play a crucial role in facilitating communication between devices. Through the LAN, devices can exchange data packets, enabling users to send emails, access websites, and transfer files. This communication infrastructure is essential for enabling collaboration and productivity in modern workplaces.- LANs serve as the backbone of local communication networks, enabling devices within a small geographical area to connect and interact seamlessly. By providing a platform for resource sharing and communication, LANs play a vital role in modern computing environments.
